Along with several other new software features demoed at its event in New York today, Samsung showed off a Smart Scroll utility, which lets you page up or down by tilting the Galaxy S 4 in the corresponding direction. The company also demoed Air Gesture, which similarly lets you scroll without putting your fingers to the glass. Finally, a feature called Smart Pause will detect your eye movements to intelligently stop video when your gaze turns away from the screen.

With dramatics fitting of the Radio City Music Hall venue, Sammy gave us a quick look at all these features in action: at a bachelorette party, where Air Gesture lets partiers look at messages without putting down those champagne flutes; on the street, where a woman can check out that guitarist on the corner without missing a second of the latest Engadget Show and -- well, Smart Scroll is straightforward enough to speak for itself.

An AR heads-up display wasn't the only navigation hardware Pioneer showed off at CEATEC 2012. The firm also took the opportunity to tear the wraps off a new line of gesture-controlled Raku Navi GPS units. With the infrared-powered Air Gesture feature, drivers can wave their hand in front of a device to pull up a menu with commands such as setting their home or a personal haunt as a destination or skipping to the next tune on a playlist. Once a hand is retracted, the menu will be replaced with the usual map interface. Though the solution isn't completely hands-free, horizontal hand waves can be assigned one of ten different functions. Japanese store shelves will be lined with two dashboard-embeddable units by mid-October, while four console-independent models will join them in early November. As of now, there's no word if the hardware will make the pilgrimage stateside.
